PHARMACOTHERAPEUTIC CATEGORY
Anti-vertigo preparations
THERAPEUTIC INDICATIONS
Prophylactic treatment of migraine with frequent and severe attacks, limited to patients who have not responded to other therapies or in whom these therapies have caused serious undesirable effects.
Contraindications When Fluxarten should not be used
Flunarizine is contraindicated in patients with:
- known hypersensitivity to flunarizine or to any of the excipients contained in the composition
- current depressive illness or history of recurrent depression
- pre-existing symptoms of Parkinson's disease or other extrapyramidal disorders
Precautions for use What you need to know before taking Fluxarten
Extrapyramidal and depressive symptoms, parkinsonism
Flunarizine can cause extrapyramidal and depressive symptoms and highlight parkinsonism, especially in elderly patients. Therefore it should be used with caution in such patients. The recommended doses should not be exceeded. Patients should be observed at regular intervals, especially during maintenance therapy, so that extrapyramidal or depressive symptoms can be detected early and, if present, treatment can be stopped.
Fatigue
In rare cases, fatigue may progressively increase during flunarizine therapy. In these cases, therapy should be discontinued (see Undesirable Effects).
Interactions Which drugs or foods can modify the effect of Fluxarten
Tell your doctor or pharmacist if you have recently taken any other medicines, even those without a prescription.
Alcohol, hypnotics or tranquilizers
Concomitant intake of flunarizine with alcohol, hypnotics or tranquilizers can cause excessive sedation.
Topiramate
The pharmacokinetics of flunarizine are not affected by topiramate. Following repeated doses to migraine patients, the systemic exposure to flunarizine was increased by 14%. When flunarizine was administered concomitantly with topiramate 50 mg every 12 hours, administration of repeated doses resulted in a 16% increase. in systemic exposure to flunarizine The steady-state pharmacokinetics of topiramate are not affected by flunarizine.
Other anti-epileptic drugs
Chronic administration of flunarizine does not affect the availability of phenytoin, carbamazepine, valproate or phenobarbital. Plasma concentrations of flunarizine were generally lower in patients with epilepsy taking these anti-epileptic drugs compared to healthy subjects given similar doses. Plasma protein binding of carbamazepine, valproate or phenytoin is not affected by concomitant administration of flunarizine.
Warnings It is important to know that:
Fertility
No data are available.
Pregnancy
Ask your doctor or pharmacist for advice before taking any medicine. As a precautionary measure, it is preferable to avoid using flunarizine during pregnancy. There are no data on the use of flunarizine in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal / fetal development, parturition or postnatal development.
Feeding time
A decision to discontinue breast-feeding or to continue / discontinue flunarizine therapy must be made taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman. It is not known whether flunarizine is excreted in human milk. Animal studies have shown excretion of flunarizine in breast milk.
Effects on ability to drive and use machines
Since somnolence may occur, especially at the start of treatment, caution should be exercised during activities such as driving vehicles or operating hazardous machinery.

05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: anti-vertigo preparations, ATC code: N07CA03
Mechanism of action and pharmacodynamic effects
Flunarizine is a bifluorinated derivative of cinnarizine with antihistamine and CNS depressant properties.
Flunarizine is a WHO class IV calcium channel blocker. It has no effect on contractility and cardiac conduction.
Flunarizine also possesses a "neuroleptic type action which could be the cause of certain side effects on the central nervous system.
05.2 Pharmacokinetic properties
Absorption
In healthy volunteers, following a single oral dose of flunarizine, peak plasma is reached after 2-4 hours. During chronic treatment, for administration of a daily dose of 10 mg, plasma concentrations gradually increase until the steady state concentration is reached around the 5th-6th week of drug intake. At steady-state, plasma levels remain nearly constant in a range between 39 and 115 ng / ml.
Distribution
The pharmacokinetic parameters of flunarizine are characterized by a large volume of distribution (apparent volume of distribution = 43.2 l / kg) in healthy volunteers and by a high tissue distribution. The results of animal experiments show that drug concentrations in various tissues they are much higher than the corresponding plasma levels, particularly in adipose tissue and skeletal muscles.
About 0.8% of flunarizine is present in free plasma, as it binds 90% to plasma proteins and 9% to erythrocytes.
Metabolism
Flunarizine is extensively metabolised in the liver (N-oxidative hydrodealkylation, aromatic hydroxylation and glucuronidation).
Elimination
Only a negligible amount of the drug is excreted unchanged in the urine.
Flunarizine and its metabolites are excreted with the faeces via the bile. In "humans," the mean terminal elimination half-life is approximately 18 days.
Clinical studies
They are not relevant to this medicine.
05.3 Preclinical safety data
For acute administration
LD50 Topo Swiss, per os: 815 mg / kg
LD50 Topo Swiss, intra peritoneal: 174 mg / kg
DL50 Ratto S.D. per os: 312 mg / kg
DL50 Ratto S.D. intra peritoneal: 353 mg / kg
For prolonged administration
S.D. rat, per os (18 months) weight decrease to 80 mg / kg / day
Beagle dog, per os (12 months) no alteration at 20 mg / kg / day
Fetal toxicity
Absent (Ratte S.D., rabbits N.Z.)
Flunarizine has no chemical analogy with compounds recognized as carcinogens and cocarcinogens. In the long-term studies (rat and dog) there were no histological manifestations or any suspected biochemical activities.
